Transmission fluid is almost black - Cars & Trucks

follow this steps and fix it. God bless you
First, check the transmission fluid level and condition. If you don't know how to do it, here is an illustration:
How to check the automatic fluid
With the engine idling and transmission in "Park" (some car may have different procedure, refer to the owner's manual) remove the automatic transmission dipstick and wipe it out with the clean lint-free cloth. Insert the dipstick back fully and then pull it out again. Check the fluid level; low level may indicate a transmission leak. Look at the fluid very closely. It helps if you drip the fluid onto a white paper to be able to see the fluid condition. The transmission fluid should be clean and transparent, without any metal filings or black flakes. The new fluid usually comes red. Over the time, it become more brownish, but it shouldn't be very dirty or black. Look at the image. Try to smell the transmission fluid; It should not have a burnt smell.
All this may seem difficult, but when you check few similar cars, you'll be able to see the difference. If the transmission fluid is too dirty or black, or smells burnt, it's better to avoid such a car.
Keep in mind, however, that some modern cars don't have the transmission dipstick and require special procedure performed in the auto repair shop to check the fluid level. In this case, the only way to check the transmission is on test drive.

The most common transmission problem on a Nissan pickup is operating the truck with the transmission fluid low. Nissan owners needs to pull the dip-stick and see if the level is low. The fluid level must be checked when the truck engine is idling. Nissan pickup owners also need to look at the color of the fluid and see if it needs to be changed or just leveled off. The color must be transparent and not black or brownish in color. The owner must also smell the transmission fluid to see if the fluid smells burnt. If the transmission fluid smells burnt, then the transmission fluid must be changed as soon as possible. Over-filling the transmission fluid level also creates Nissan pickup transmission problems.

The transmission is probably toast from overheated fluid (burnt). That is how transmission fluid turns a very dark color.
You should get a second opinion, but I doubt that a drain and refill will restore the transmission.

Well, lets see... it could be engine oil, it could be coolant/antifreeze, it could be brake fluid, it could be power steering fluid, it could be windshield washer fluid, it could be transmission fluid, it could be gas, it could be differential gear oil.

DONT DRIVE IT ANOTHER INCH. Black transmission fluid poor shifting you're close to a $3000 dollar repair bill because you have gone too long with out a fluid change. Don't flush it just change the fluid and if it has one the filter in the transmission pan. Youtube the procedure or get the repair manual. You have to do it your self or have it towed that's how seriously close you are to transmission failure. Big bucks

The mechanics lied to you. Changing the transmission fluid and screen will not cause any car not to run. Just as you need to periodically change the oil, the same holds true for transmission fluid. Though the fluid is black, yoou state that you have no slippage or nothing out of the ordinary. If that is the case, then you do not need a new transmission. Just have the fluid and screen replaced and all will be fine. Make sure to pick up a transmission pan gasket while you get the necessary fluid and screen. Again, changing the fluid will not cause any car to not run. It is safe to perform the fluid change.

To fill the transmission fluid, you need a funnel that fits into the dipstick tube, add fluid there. If the fluid is black and smells burnt, that's bad. I would have the fluid changed. These transmissions don't have a filter, probally a bad idea.

if the transmission oil is black is either someone accidently put oil in the transmission or the transmission is due for some serious service. have the transmission flushed as soon as possible. Transmission fluid should be red in color. usually if it is a dark red almost black and smells burned the transmission has been worked very hard.

Draining the transmission fluid and replacing it with fresh and new fluid is where to start ..
